A british United Nations boss was found frozen to death after a booze bender in Vienna.

John McFadzean, 26, is thought to have fallen asleep on a park bench in the Austrian capital after his wallet was stolen in a bar.

He had been attending a UN conference and joined delegates to down Schnapps and beer till 6.30am.

But the drunken international development expert, finding he had no money, then wandered the city trying to find his hotel.

Three hours later he was found dead in the freezing park several miles from the bar.

Police believe he had got lost and tired so decided to have a sleep.

The tragedy was in September and police originally withheld details to respect the privacy of his family.

But over the weekend they went public so officers could appeal for help to catch the thief. Now they have arrested a Polish man in connection with the incident after almost £600 in transport tickets were bought using Mr McFadzean's credit cards.

Inspector Martin Baier said: "Thanks to that appeal over the weekend we have arrested a Polish national who admitted to taking the wallet."

Mr McFadzean, from Warrington in Cheshire, had been in Vienna for an Industrial Development Organisation conference.
